Note : this replaces the previously released v4.0.

Why Kerberos?

Kerberos authentication provides a highly secure method to authenticate client and server entities (security principals) on a network. To use Kerberos authentication with SQL Server, a Service Principal Name (SPN) must be registered with Active Directory, which plays the role of the Key Distribution Center in a Windows domain. In addition, many customers also enable delegation for multi-tier applications using SQL Server. In such a setup, it may be difficult to troubleshoot the connectivity problems with SQL Server when Kerberos authentication fails.

Here are some additional reading materials for your reference.
